Help !! - Water quality questions !

So you have 800 ppm calcium coming from your RO unit before adding salt?
Let the ro unit break Ina bit
You should read 7.0 ph ans zero calcium it should basically take everything out of the water
Try another calcium test kit your may be faulty which brand are you using

I think there is something wrong with your test kit or maybe you made a mistake testing. That doesn't make sense even if it is a brand new RO/DI unit. How much RO/DI water have you made with this new unit?

[fishmanty]

That is quite the cycle up for Calcium. I'd assume your RO unit isn't removing the calcium at all. Do you do water changes or just top up the evaporated water?

Hmmm...I was just thinking here...do you by chance have your good water and waste water lines mixed up? Try testing the other line. Going from 50 ppm calcium to 800 ppm calcium almost seems like it is the waste water concentration.

One more thing...why are you testing calcium instead of using a calibrated TDS meter? TDS meters are cheap.

good call Myka.

Ive seen tds meters at Walmart for like $10

This is highly unlikely to have 50 ppm of calcium at the input of the osmosis unit and then it come out at 800ppm?? where is it coming from? I don't see anything in a standard unit that could leak calcium. ???

Either you have the output and input mixed up or your test is not good.

If you really have 650ppm of calcium in your tank, this is much too high.

Another thought...is the calcium test you're using compatible with freshwater?
